The ZyWALL 10 is a dual Ethernet Internet Security Gateway integrated with robust firewall solutions and network management features that allows access to the Internet via Cable/ADSL modem or Internet router. It is designed for:

!Home offices and small businesses with Cable, xDSL and wireless modem via Ethernet port as Internet access media.

!Multiple office/department connections via access devices.

!E-commerce/EDI applications.

Your ZyWALL 10 is easy to install and configure.

The ZyWALL Web Configurator (Web Configurator) is a web-based utility that allows you to access the ZyWALL’s management settings and configure the firewall. Most functions of the ZyWALL 10 are also software configurable via the SMT (System Management Terminal) interface. The SMT is a menu-driven interface that you can access from a terminal emulator through the console port or over a telnet connection.

You can configure most features of the ZyWALL 10 via SMT but we recommend you

configure the firewall using the ZyWALL Web Configurator.
